我局在齐齐哈尔车站新建候车室的设计与施工中,首次采用了高温热水采暖系统。该系统于1980年4月进行了试运行。一、概况该候车室建筑面积为16,600米~2,采暖热负荷为113万千卡/小时。设计送水温度为120℃,回水温度为70℃。全系统(包括锅炉和室外管道)总容水量为40米~3。系统最高点达39米。散热器全部采用了钢串片式散热器。管道连接除标高13.5米以上支管采用了丝接外,其余一律采用焊接。
During the design and construction of the new waiting room at the Qiqihar station, our bureau adopted the high-temperature hot water heating system for the first time. The system was commissioned in April 1980. I. Overview The waiting room has a building area of 16,600 m2 and a heating heat load of 1.13 million kcal/hour. The designed water delivery temperature is 120°C and the return water temperature is 70°C. The total water capacity of the whole system (including boilers and outdoor pipes) is 40 m~3. The highest point of the system is 39 meters. Radiators are all made of steel string radiators. In addition to the 13.5 meters above sea level, the pipe connection adopts the wire connection, and the rest are all welded.
